What is the 7 7 rule for tires?
The 7 7 rule for tires provides a simple temperature guideline for timing your seasonal tire changes. Install winter tires when daily temperatures drop to 7°C (45°F) or below for seven consecutive days. Remove them in spring after seven straight days above 7°C. As mentioned above, Transport Canada advises Canadian drivers not to use winter tires with a tread depth of less than 5/32”, or roughly 70 percent worn. This is similar to what most tire manufacturers recommend and even what most provinces dictate by law.Cons: Compromised Traction: May struggle in heavy snow or severe winter conditions, as they aren’t explicitly designed for such situations. Shorter Lifespan: Compared to dedicated winter or summer tires, all-weather tires might wear out faster when exposed to extreme temperature fluctuations.
